DC1 Frequency Inverter 10/12 MN04020003Z-EN www.eaton.com 51
Table 4: Minimum clearance and required cooling air
The values in 4 are recommended values for an ambient air temperature of
up to +50 °C, an installation altitude of up to 1,000 m, and a pulse frequency
of up to 8 kHz.
Figure 26: Minimum required clearance
in front of the frequency inverter
When frequency inverters with internal fans are installed vertically over each
other, an air baffle must be placed between the devices. Failure to do so may
expose the device on top to a thermal overload caused by the guided air flow
(device fan).

1) For UL conformity, the maximum permissible ambient air temperature over a period of 24 hours is limited to
+45 °C for the DC1-127D0…, DC1-32011…, and DC1-32018… frequency inverters.
￫
Typical heat loss makes up about 3 % of the operational load
conditions.
￫
Please note that the mounting makes it possible to open and
close the control signal terminal covers without any problems.
